摘要： 以格日滑坡为研究对象，根据滑坡的基本特征以及地质环境条件，对其成因机制进行分析。同时通过定性与定量分析，对格日滑坡的稳定性进行研究，在三种不同工况下对格日滑坡进行了稳定性计算。计算结果发现：格日滑坡整体在天然状态下处于基本稳定的状态，在强降雨和地震状态下处于欠稳定的状态，在其影响下滑坡很可能发生整体滑动，需要采取合理的防治措施进行治理。

Abstract: This paper presents the analysis results of Geri Landslide. Based on the characterizing of the landslide and the site geological conditions, the landslide triggering mechanism was also evaluated. Throughout the qualitative and quantitative analyses, the stability of Geri landslide is further studied, and the stability of Geri landslide is investigated under three different working conditions. The results show that the body of the Geri landslide is generally stable in the natural condition but is instable under the heavy rainfall and earthquake conditions. Under these adverse influence factors, the landslide body is likely to slid and landslide mitigation measures are needed.

Key words: landslide, triggering mechanism, stability evaluation
